Answer:

1555 people

Step-by-step explanation:

First, average the votes for polar bears.

(46 + 43 + 49)/3 = 46

Next, make the variable x equal to the estimate of the number of people who will prefer polar bear out of the 3380 people and set up your proportion equation.

x/3380 = 46/100

x = 1554.8

Round to the nearest whole number to get 1555.

How I can solve this
gavmur [86]

Answer:

\boxed{\textrm{B)}\qquad y>4}.

Step-by-step explanation:

We start by subtracting 1 from both sides of the second inequality:

2x > 5 \iff 2x - 1 > 5 - 1 \iff 2x - 1 > 4.

Therefore, we conclude that:

y > 2x - 1 > 4 \implies y > 4.

Therefore, every point that satisfies the system has a y-coordinate greater than 4.
